Military's Tiny Implant Could Give People Self-Healing Powers


If a tiny device could be implanted in your body to give you self-healing powers, would you want one?

That question is on many minds now that the Defense Department's Advanced Research Projects Agency (DARPA) has announced that just such a device is in the works: an electronic implant, injected via a needle, that would monitor the health of internal organs and help the body heal itself when illness or injury strikes.

Sunflower-Shaped Dish Makes Power, Fresh Water


Generating electricity from sunlight is nothing new. But now IBM in partnership with Airlight Energy has found a way to tackle two problems at once. They’ve developed 30-foot sunflower-shaped solar concentrators that can generate electricity while at the same time desalinate water to make it drinkable. The double-duty utility of the technology could work best in hot climates where fresh water is scare.

Turning the Moon into a cosmic ray detector


Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays -- the most energetic particles in the Universe. The origin of UHE cosmic rays is one of the great mysteries in astrophysics. Nobody knows where these extremely rare cosmic rays come from or how they get their enormous energies. Physicists detect them on Earth at a rate of less than one particle per square kilometer per century.

Did the Vikings Get a Bum Rap?


The Vikings gave no quarter when they stormed the city of Nantes, in what is now western France, in June 843—not even to the monks barricaded in the city's cathedral. "The heathens mowed down the entire multitude of priest, clerics, and laity," according to one witness account. Among the slain, allegedly killed while celebrating the Mass, was a bishop who later was granted sainthood.

Remarkable Limb Regeneration Began 300 Million Years Ago


Fossilized, primitive amphibians with odd-looking appendages, some with extra toes and deformed shapes, suggest the ability of some vertebrates to regenerate or regrow amputated limbs first evolved at least 300 million years ago.

Salamanders are the only modern four-legged vertebrates, or animals that have backbones, able to fully regenerate their limbs into adulthood.

How Diversity Makes Us Smarter


The first thing to acknowledge about diversity is that it can be difficult. In the U.S., where the dialogue of inclusion is relatively advanced, even the mention of the word “diversity” can lead to anxiety and conflict. Supreme Court justices disagree on the virtues of diversity and the means for achieving it. Corporations spend billions of dollars to attract and manage diversity both internally and externally, yet they still face discrimination lawsuits, and the leadership ranks of the business world remain predominantly white and male.

Paralysed rats takes 1,000 steps thanks to remote-controlled technology


A team at the the École Polytechnique Fédérale in Switzerland has restored movements to entirely paralysed rats, allowing them to walk fluidly on their hind legs while their upper bodies are supported by a tiny harness. The technique involves zapping the rat’s spinal cord with electrical pulses to replace the commands that are normally sent out by the brain, but are obscured when the spine is severely injured.

Mantis shrimps can see cancer, and scientists have now created a camera that does the same


Scientists from the University of Queensland in Australia have discovered that mantis shrimp have an incredibly useful ability - the marine creatures are able to see a variety of cancers inside our bodies. And they've now replicated that ability in a camera that could eventually be put into a smartphone.

Brain scans reveal 'gray matter' differences in media multitaskers


Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research. People who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally.

Diet affects sperm competitiveness


It's well known that omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) can help to prevent heart disease but new research has found that these essential fatty acids can also increase the chance of paternity success.

The results published today in the Royal Society journal Biology Letters looked at the guppy Poecilia reticulata, a live-bearing fish with a highly promiscuous mating system in which sperm typically compete for fertilisations.
